When I bought the car, it came with a Riss Racing oil catch can. Good news, right? Well, not so much. After realizing how small the lines were, I couldn’t stop thinking about it. Why wouldn’t they utilize the large lines that the stock PCV system had? Plus, it’s mounted on the hot side, right on top of the turbos! Definitely a re-branded eBay part.
Anyways, I bought a BMS OCC because it’s built from the ground up specifically for this car. It’s hoses exceed the OEM PCV piping in diameter and that flow rate is maintained throughout the entire catch can ensuring no excessive crankcase pressure buildup. Unlike the Riss Racing can, the BMS version is mounted on the cold side underneath the cowl for a stealthy look. Holding the two, the BMS oil catch can is the winner, hands down. Gotta love Terry’s products.
Much better. The hoses are nice and thick and you can’t even see it once the cowl is back on. Very happy with the upgrade.
